To accurately evaluate the level of vehicle intelligence and guide product iteration, this paper develops an intelligent user evaluation index system based on the Product Leadership Attribute Leading strategy (PALS) framework, covering 3 dimensions including product, technology, and corporate image. It introduces the LACU competitive evaluation strategy and conducts an empirical analysis with 1 521 purchase decision makers assessing a subject vehicle model and 5 competing models. The results show that the subject vehicle achieves an L (Leading) rating in 2 indicators:"leading intelligent interaction technology" and "owning an independent intelligent technology brand," which constitute its differentiated advantages. However, it receives a U (Uncompetitive) rating in 5 indicators, including"leading intelligent driving technology,"indicating notable weaknesses. The study confirms that the LACU evaluation system can effectively quantify a product's competitive position in the field of intelligence, identify strengths and shortcomings, and provide a scientific basis for automakers to define priorities in technological iteration and optimize resource allocation.
